ABSTRACT:
A method and system for reducing power consumed by a computer system. A network switch includes a processor coupled to a plurality of ports which are coupled to a plurality of computer systems. The processor includes logic for receiving a media access control address from one of the computer systems. The computer system may later enter into either a hibernation state or an off state. The processor may further include logic for receiving a magic packet that includes a repetitive address that identifies the computer system. Upon receiving the magic packet, the processor remotely activates the computer system from either the hibernation state or the off state. By remotely activating the computer system, the computer system may consume less power since the network subsystem in the computer system may not need to monitor for a magic packet. Instead, the magic packet may be monitored by the network switch.
